Nick celebrated his birthday last week, and Frankie took to Instagram to share a sweet message to his big brother: “Happy birthday bro,” Frankie wrote. “You have and always will be one of my biggest inspirations and supporters. Appreciate all the things you’ve done for me and all the times you’ve been there for me as one of my closest and best friends. Love you always. To many more! I’m lucky to have you as a brother and a friend homeskillet.”
